[PATCH] D153556: [OPENMP52] Initial support for doacross clause.

[Alexey Bataev via Phabricator via cfe-commits]

ABataev added inline comments.


================
Comment at: clang/lib/Parse/ParseOpenMP.cpp:4415-4439
+  } else if (Kind == OMPC_doacross) {
+    // Handle dependence type for the doacross clause.
+    ColonProtectionRAIIObject ColonRAII(*this);
+    Data.ExtraModifier = getOpenMPSimpleClauseType(
+        Kind, Tok.is(tok::identifier) ? PP.getSpelling(Tok) : "",
+        getLangOpts());
+    Data.ExtraModifierLoc = Tok.getLocation();
----------------
Can it be unified with depenbd clause parsing? (Maybe in a separate template function)


================
Comment at: clang/lib/Sema/SemaOpenMP.cpp:91
       llvm::SmallVector<std::pair<Expr *, OverloadedOperatorKind>, 4>;
-  using DoacrossDependMapTy =
-      llvm::DenseMap<OMPDependClause *, OperatorOffsetTy>;
+  using DoacrossDependMapTy = llvm::DenseMap<OMPClause *, OperatorOffsetTy>;
   /// Kind of the declaration used in the uses_allocators clauses.
----------------
DoacrossClauseMapTy? Since it is intended to handle also doacross clauses.


================
Comment at: clang/lib/Sema/SemaOpenMP.cpp:11299-11344
       if (DC->getDependencyKind() == OMPC_DEPEND_source) {
         if (DependSourceClause) {
           Diag(C->getBeginLoc(), diag::err_omp_more_one_clause)
               << getOpenMPDirectiveName(OMPD_ordered)
               << getOpenMPClauseName(OMPC_depend) << 2;
           ErrorFound = true;
         } else {
----------------
Try to avoid copy-paste. Maybe introduce templated function?


================
Comment at: clang/lib/Sema/SemaOpenMP.cpp:11359-11371
+  } else if ((DependFound || DoacrossFound) && (TC || SC)) {
+    SourceLocation Loc =
+        DependFound ? DependFound->getBeginLoc() : DoacrossFound->getBeginLoc();
+    Diag(Loc, diag::err_omp_depend_clause_thread_simd)
+        << getOpenMPClauseName(DependFound ? OMPC_depend : OMPC_doacross)
         << getOpenMPClauseName(TC ? TC->getClauseKind() : SC->getClauseKind());
     ErrorFound = true;
----------------
Same, try to avoid copy-paste


================
Comment at: clang/lib/Sema/SemaOpenMP.cpp:24002
+
+OMPClause *Sema::ActOnOpenMPDoacrossClause(
+    OpenMPDoacrossClauseModifier DepType, SourceLocation DepLoc,
----------------
Same, if possible try to unify handling with the depend clause, if possible
